This is a complete set of all 20 volumes of Atsushi Kaga's popular shonen manga, "Kuro Ageha." I purchased this on Mercari this summer and have read it once. It doesn't appear to be from a manga cafe or a rental. The pages are yellowing somewhat, but it doesn't affect readability at all. I don't think there's any smell of old books either. However, this is just my subjective opinion, so please forgive any oversights. Thank you for looking.
